Answer:
Option (4).
Explanation:
Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.
The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.
Thus, the correct answer is option (4).
Meiosis would be the name of the cell process.
The DNA migrated to the positive pole of the electrophoresis chamber because the DNA's chemical structure is negative.
As we know, opposite attracts. Negative is attracted to positive, that is why the DNA migrated to the positive pole of the electrophoresis chamber.
Answer:
The formula for solving density is:
p=m/v
p= 45/15
p= 3 g/cm^3
